This elegant shell was long ago distinguished by Chemnitz from S. Auris Dianse, 

 with which it has doubtingly been associated by Dilwyn and other conchological 

 writers. The smoothness of the inner lip of the latter species would, of itself alone, 

 enable us to separate the two, but this indeed is far from being the sole distinctive 

 difference. 



The Pacific Strombus is of a pale satin-like fa^vn colour, mottled with white, the 

 shape ovate oblong, slightly nodulovis and ribbed towards the base, with a range of 

 sharpish protuberances at the upper angle of the body-whorl, running up the exserted 

 spire, which is somewhat longer in proportion than that of Am-is Dianse. The outer 

 lip, as in that shell, has its summit produced into a digitiform lobe, but the throat is 

 deeply furrowed. The pillar lip is pure white, with the higher portion of it stained 

 not inelegantly by a large chesnut-coloured spot ; and the beak at the base of the 

 aperture is long, tapering and ascending. If we may believe MartjTi it is brought 

 to us from the Fi-iendlv Isles, and in length is about three inches.

Testa ovato-oblonga, transversim sulcata, tuberculato-nodosa ; grisea, lineis fuscis longi-

The general shape, the digitation of the lip, the exserted spire and ascending 

 beak, might lead us to confound this with the preceding species; but the smooth and
